lace wyandotte crosses

Good evening all....I purchased these 2 hens from a poultry tailgate. I was told the black one is a lace wyandotte/ black jersey cross. But the grey one was called a mutt. I believe she has silver lace wyandotte in her, but cannot determine what else. Any clues??

Here are more pictures of Rosabella. Maybe these will be better for identification... she does seem to have the comb of an EE.... and her leg color matches her body color....very pale whitish grey with pink undertones

Okay, so I have come to the conclusion that she is probably a cross of SLW, EE and Faverolle.... seems she has characteristics of all 3 and the gentleman did say she was a mutt and not just a 2 way cross. Thanks for everyone's help on this bird.
